[Bug 1565141] Re: Crash on applying ChromaKey

 

Happening for me on windows 10, ryzen 1800x, nv1060.
I can add the chroma effect and preview, until i slow the clip down, then openshot will crash when i try to preview the clip

Title:
  Crash on applying ChromaKey

Status in OpenShot Video Editor:
  New
Status in openshot package in Ubuntu:
  New

Bug description:
  Ubuntu 14.04 x64
  RAM: 8GB
  Processor: Intel Core i5 CPU M 540 @ 2.53GHz x4
  Graphics: NVS 5100M/PCIe/SSE2
  Version of Openshot: 2.0.6 (Installed via PPA) & 2.0.7 (ran using downloaded .appimage)
  BZR Revision used (if any) : ?? not sure, can't find any packages called BZR
  MLT/melt version: libmlt6     0.9.3+git20141005.22abed67-0ubuntu0~sunab~trusty1   amd64
  FFmpeg (i.e.libavcodec) version : libavcodec54:amd64      6:9.18-0ubuntu0.14.04.1  amd64
  FFmpeg installation : libxine2-ffmpeg 1.2.4-2ubuntu1   amd64

  Steps to reproduce issue:
  Open Openshot
  import video / open saved project.
  switch to effects tab
  drag Chroma effect to video in timeline. 
  double click chroma color
  click "Pick Screen Color" button
  click spot on preview panel
  click OK. *** sometimes crashes here ***
  double click Fuzz, set new value, hit tab. *** sometimes crashes here ***

  
  Part of what is odd about this error is sometimes if I hit save between each step I can keep moving forward with adding new chroma effects. Because my bluescreen is not very good I'm having to build several chroma effects on the video in an attempt to remove all of the color variations. the issue starts happening more often the more chroma effects I add. If I keep saving my project after each change I'm sometimes able to add more chroma effects after I reopen the project file. But at some point ~15 chroma effects added to a video track it just keeps crashing after hitting ok on the color picker dialog. I've also been able to reproduce the issue running as my normal user and under SUDO. The orignal videos were recorded using my phone camera in MP4 format. I've tried a couple different recordings with the same results the general video info is below:

  Video:
  Length: 1 minute 1 second
  Container: Quicktime
  Dimensions: 1920x1080
  Codec: H.264
  Framerate: 30fps
  Bitrate: 17077 kbps

  Audio:
  Codec: MPEC-4 AAC
  Channels: Stereo
  Sample rate: 48Khz
  Bitrate: 96 kbps

  
  If you need any additional details please let me know.

  Last several console lines from a couple different crashes, gathered
  by running 2.0.7 from terminal.
